Credential Consumer Identities

This page is the technical reference for credential consumer identities — the key-value maps OCM uses to look up credentials for a given operation. For a high-level introduction, see Credential System.

For the credential types that go in the credentials: field of each consumer entry, see Reference: Credential Types.

Overview

Every time OCM needs credentials (accessing a registry, signing a component version), it constructs a **lookup identity ** — a map of string attributes describing what it needs credentials for. The credential system then searches configured consumers for a matching entry.

A consumer entry in .ocmconfig looks like this:

type: generic.config.ocm.software/v1
configurations:
  - type: credentials.config.ocm.software
    consumers:
      - identity:
          type: <identity-type>
          # ... type-specific attributes
        credentials:
          - type: Credentials/v1
            properties:
            # ... key-value credential properties

The consumer identity type is extensible — any string in Name or Name/Version format can be used. Plugins and integrations can introduce additional types (e.g. AWSSecretsManager, HashiCorpVault, MavenRepository). The following types are defined by the core OCM modules:

Identity TypeUsed For
OCIRegistryAuthenticating against OCI registries
HelmChartRepositoryAuthenticating against Helm chart repositories
WgetAuthenticating against plain HTTP/HTTPS servers
GitHubRepositoryAuthenticating against the GitHub REST API
RSA/v1alpha1Providing signing and verification keys

OCIRegistry

Used when OCM accesses an OCI registry — pushing, pulling, or resolving component versions and resources.

Identity Attributes

AttributeRequiredDescription
typeYesMust be OCIRegistry
hostnameYesRegistry hostname (e.g. ghcr.io, registry.example.com)
pathNoRepository path. Supports glob patterns (* matches one path segment). If omitted, matches any path on the hostname.
schemeNoURL scheme (https, http, oci). If omitted, matches any scheme. If set, must match exactly.
portNoPort number as string. Default ports are applied when scheme is set: https and oci default to 443, http defaults to 80.

Credential Properties

PropertyDescription
usernameUsername for basic authentication
passwordPassword for basic authentication
accessTokenBearer token sent directly to the registry (Docker token flow)
refreshTokenOAuth2 refresh token exchanged for an access token before each request

Token fields take precedence over username/password when both are present. Use OCICredentials/v1 for the full typed field reference.

Matching Behavior

Matching runs three chained checks — all must pass:

  1. Path matcher — compares path using path.Match (glob). * matches one segment, not across /. If the configured entry has no path, any request path is accepted.
  2. URL matcher — compares scheme, hostname, and port. Applies default ports when a scheme is present ( https443, http80).
  3. Equality matcher — all remaining attributes (like type) must be exactly equal.

For detailed matching examples and edge cases, see Tutorial: Understand Credential Resolution.

Examples

Hostname only — matches all paths on ghcr.io:

- identity:
    type: OCIRegistry
    hostname: ghcr.io
  credentials:
    - type: OCICredentials/v1
      username: my-user
      password: ghp_token

Hostname + path glob — matches any single-segment path under my-org/:

- identity:
    type: OCIRegistry
    hostname: ghcr.io
    path: my-org/*
  credentials:
    - type: OCICredentials/v1
      username: org-user
      password: ghp_org_token

Hostname + scheme + port — matches only HTTPS on a custom port:

- identity:
    type: OCIRegistry
    hostname: registry.internal
    scheme: https
    port: "8443"
  credentials:
    - type: OCICredentials/v1
      username: internal-user
      password: internal_pass

HelmChartRepository

Used when OCM accesses a remote Helm chart repository — pulling or resolving Helm charts referenced as resources. The identity is derived from the Helm repository URL using the same URL-based attributes as OCIRegistry.

Identity Attributes

AttributeRequiredDescription
typeYesMust be HelmChartRepository
hostnameYesRepository hostname (e.g. charts.example.com, registry.example.com)
pathNoRepository path (e.g. stable). If omitted, matches any path on the hostname.
schemeNoURL scheme (https, http, oci). If omitted, matches any scheme.
portNoPort number as string. If omitted, matches any port.

Credential Properties

PropertyDescription
usernameRepository username
passwordRepository password or token

Examples

HTTPS Helm repository:

- identity:
    type: HelmChartRepository
    hostname: charts.example.com
    path: stable
  credentials:
    - type: HelmHTTPCredentials/v1
      username: helm-user
      password: helm-token

OCI-based Helm repository:

- identity:
    type: HelmChartRepository
    hostname: registry.example.com
    scheme: oci
  credentials:
    - type: OCICredentials/v1
      username: registry-user
      password: registry-token

Wget

Used when OCM fetches a resource over plain HTTP or HTTPS through the Wget/v1 access type and the Wget/v1 input type. The identity is derived from the resource url; the access type and the input type derive it identically, so a single consumer entry covers both.

Identity Attributes

AttributeRequiredDescription
typeYesMust be Wget
hostnameYesServer hostname (e.g. downloads.example.com)
pathNoURL path without the leading /. Supports glob patterns (* matches one path segment). If omitted, matches any path on the hostname.
schemeNoURL scheme (https, http). If omitted, matches any scheme. If set, must match exactly.
portNoPort number as string. During matching, default ports are applied when scheme is set: https defaults to 443, http to 80.

Example derivation: for url: https://downloads.example.com/myapp/1.0.0/myapp.tar.gz, the lookup identity is:

AttributeValue
typeWget
hostnamedownloads.example.com
schemehttps
pathmyapp/1.0.0/myapp.tar.gz

The URL carries no explicit port, so no port attribute is derived. Default ports stay implicit in the identity and are applied by the URL matcher instead, so this identity matches a consumer entry with port: "443" as well as one with no port at all. A URL that names its port (https://downloads.example.com:8443/...) does derive port: "8443".

Credential Properties

PropertyDescription
usernameUsername for HTTP basic authentication
passwordPassword for HTTP basic authentication
identityTokenBearer token sent as Authorization: Bearer <token>. Takes precedence over Basic Auth.
certificatePEM-encoded client certificate for mutual TLS
privateKeyPEM-encoded private key paired with certificate
certificateAuthorityPEM-encoded CA certificate used to verify the server certificate. Only applied together with certificate.

Use WgetCredentials/v1 for the typed field reference.

Basic Auth and a bearer token both set the Authorization header and are therefore mutually exclusive. When both are configured, the bearer token wins and a warning is logged. The mutual TLS certificate is a transport-layer credential and combines with either of them, but it only takes effect during a TLS handshake: supplying one for an http:// URL logs a warning and has no effect.

Matching Behavior

The same three chained checks as OCIRegistry apply: path glob, URL (scheme, hostname, port with default-port handling), then exact equality on the remaining attributes.

The identity type is matched by exact string and is unversioned, so it must be written as type: Wget. Neither Wget/v1 (the name of the access and input type) nor the lowercase wget used by OCM v1 will match. A non-matching entry fails silently: no credentials are resolved and the request goes out unauthenticated, so the symptom is a 401 from the server rather than a configuration error.

Examples

Hostname only. Matches every download from that host:

- identity:
    type: Wget
    hostname: downloads.example.com
  credentials:
    - type: WgetCredentials/v1
      username: download-user
      password: download-token

Bearer token for a single path segment (matches artifacts/build.zip, not artifacts/ci/build.zip):

- identity:
    type: Wget
    hostname: api.example.com
    scheme: https
    path: artifacts/*
  credentials:
    - type: WgetCredentials/v1
      identityToken: eyJhbGciOi...

Mutual TLS against an internal server:

- identity:
    type: Wget
    hostname: artifacts.internal
    scheme: https
    port: "8443"
  credentials:
    - type: WgetCredentials/v1
      certificate: |
        -----BEGIN CERTIFICATE-----
        MIIDdzCCAl+gAwIBAgIEbGVnYWw...
        -----END CERTIFICATE-----
      privateKey: |
        -----BEGIN PRIVATE KEY-----
        MIIEvQIBADANBgkqhkiG9w0BAQ...
        -----END PRIVATE KEY-----
      certificateAuthority: |
        -----BEGIN CERTIFICATE-----
        MIIDQTCCAimgAwIBAgITBmyf...
        -----END CERTIFICATE-----

For migrating a Wget consumer entry from OCM v1, covering the renamed identity type, the pathprefix to path conversion, and the inverted authentication precedence, see Tutorial: Work with HTTP Resources.


GitHubRepository

Used when OCM resolves or downloads a resource with a GitHub/v1 access — resolving a ref to a commit or fetching a commit’s source archive via the GitHub REST API. The identity is derived from the access’s repoUrl. Credentials are optional; see the note on anonymous access under GitHubCredentials/v1.

Identity Attributes

AttributeRequiredDescription
typeYesMust be GitHubRepository
hostnameYesRepository hostname (e.g. github.com, a GitHub Enterprise host)
pathNoRepository path (e.g. open-component-model/open-component-model). If omitted, matches any path.
schemeNoURL scheme (https, http). If omitted, matches any scheme.
portNoPort number as string. If omitted, the scheme’s default applies (https443, http80).

Credential Properties

PropertyDescription
tokenGitHub or GitHub Enterprise access token

Examples

github.com:

- identity:
    type: GitHubRepository
    hostname: github.com
    path: open-component-model/open-component-model
  credentials:
    - type: GitHubCredentials/v1
      token: ghp_example_token

GitHub Enterprise host:

- identity:
    type: GitHubRepository
    hostname: git.example.corp
  credentials:
    - type: GitHubCredentials/v1
      token: ghe_example_token

Omitting path matches every repository on that host.


RSA/v1alpha1

Used when OCM signs or verifies component versions with RSA keys.

Identity Attributes

AttributeRequiredDescription
typeYesMust be RSA/v1alpha1
algorithmYesSigning algorithm. Must be RSASSA-PSS (recommended) or RSASSA-PKCS1-V1_5.
signatureYesLogical signature name (e.g. default). Must match the --signature flag used with ocm sign cv. Defaults to default if not specified on the CLI.

All three attributes are required. When OCM looks up signing credentials, it always constructs a lookup identity with type, algorithm, and signature. If your consumer entry omits algorithm, the credential system will not find a match — even though the signing algorithm defaults to RSASSA-PSS internally.

If you are unsure which algorithm to use, specify algorithm: RSASSA-PSS.

Credential Properties

PropertyUsed ForDescription
privateKeyPEMSigningInline PEM-encoded private key
privateKeyPEMFileSigningPath to PEM-encoded private key file
publicKeyPEMVerificationInline PEM-encoded public key
publicKeyPEMFileVerificationPath to PEM-encoded public key file

You can specify both privateKeyPEMFile and publicKeyPEMFile in the same entry to use it for both signing and verification.

When using the legacy Credentials/v1 properties: map instead of RSACredentials/v1, the old snake_case keys (private_key_pem, private_key_pem_file, public_key_pem, public_key_pem_file) are still accepted as a deprecated backward-compatibility fallback.

Matching Behavior

Unlike OCI identities, RSA signing identities use strict equality matching — every attribute in the lookup identity must be present in the configured consumer identity with the exact same value. There is no glob or subset matching.

Examples

Signing and verification with default settings:

- identity:
    type: RSA/v1alpha1
    algorithm: RSASSA-PSS
    signature: default
  credentials:
    - type: RSACredentials/v1
      privateKeyPEMFile: /path/to/private-key.pem
      publicKeyPEMFile: /path/to/public-key.pem

Multiple signature identities (e.g. dev and prod):

- identity:
    type: RSA/v1alpha1
    algorithm: RSASSA-PSS
    signature: dev
  credentials:
    - type: RSACredentials/v1
      privateKeyPEMFile: /path/to/dev/private-key.pem
      publicKeyPEMFile: /path/to/dev/public-key.pem
- identity:
    type: RSA/v1alpha1
    algorithm: RSASSA-PSS
    signature: prod
  credentials:
    - type: RSACredentials/v1
      privateKeyPEMFile: /path/to/prod/private-key.pem
      publicKeyPEMFile: /path/to/prod/public-key.pem

Sign with a specific identity:

ocm sign cv --signature dev <component-version>
ocm sign cv --signature prod <component-version>

Using PKCS#1 v1.5 algorithm:

- identity:
    type: RSA/v1alpha1
    algorithm: RSASSA-PKCS1-V1_5
    signature: legacy
  credentials:
    - type: RSACredentials/v1
      privateKeyPEMFile: /path/to/private-key.pem

Complete Configuration Example

A single .ocmconfig combining registry credentials (with Docker fallback) and signing credentials:

type: generic.config.ocm.software/v1
configurations:
  - type: credentials.config.ocm.software
    consumers:
      # OCI registry — hostname catch-all
      - identity:
          type: OCIRegistry
          hostname: ghcr.io
        credentials:
          - type: OCICredentials/v1
            username: my-user
            password: ghp_token

          signature: default
        credentials:
          - type: RSACredentials/v1
            privateKeyPEMFile: /path/to/private-key.pem
            publicKeyPEMFile: /path/to/public-key.pem
    # Docker config fallback for registries not matched above
    repositories:
      - repository:
          type: DockerConfig/v1
          dockerConfigFile: "~/.docker/config.json"

Discovering Credential Types at Runtime

Use ocm describe types credentials to list all credential types registered in your OCM installation — including any added by installed plugins — and ocm describe types credentials <type> to inspect the fields of a specific type.
